This spectacular collection of rugged ruins sprawls over a windswept plateau at a dizzying 3600 meters. The 3km-long site dates from around 400 BC and has immense defensive perimeter walls and towering ceremonial buildings. Research suggests that the complex formed a center of religious worship. Different communities from all corners of Huamachuco lands would visit to worship the gods that were believed to reside on the mountain peaks surrounding the site on all sides.
The largest archaeological site in the northern mountains, it is divided into four main sections, two of which, Cerro del Castillo and Cerro de Las Monjas, are open to visitors on a well-marked circuit.
